MACHINE FOR MAKING LINGOES.

SPECIFICATION forming part of Letters Patent No. 648,094, dated April 24, 1900.

Application filed March 27. 1899. Serial No. 710,614. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT W. BARKER, a citizen of the United States, residing at Paterson, in the county of Passai'c and State of New Jersey, have invented certain new and useful Improvements in Machines for Making Lingoes, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of my invention is to provide an improved machine to facilitate the manufacture of lingoes, to do the work now requiring several persons and machines, and to econo- Inize in time, labor, and space in said manufacture. The method in vogue is to run the wire through a machine to straighten it and cut it into lengths sufficient to make two lingoes. Another person puts these lengths in a press to flatten them in the center. They are then passed to another machine and are cut in two at the flattened portion by a die, so as to round the ends of the lingoes. Finally they go to a punching-machine, and a hole is there punched through the flattened ends.

My machine has a feed mechanism attached and performs all the operations necessary to make the completed lingo. It feeds the wire, cuts off to length, flattens the head, punches the hole, and cuts the end round and smooth.

My invention consists of a press with certain new and useful attachments in combination therewith, the peculiar construction and arrangement of the various parts and the combinations thereof being hereinafter fully described, and set forth in the claims and shown in the drawings accompanying this specification and forming a part thereof.

In the drawings like letters and numerals of reference indicate like parts in the different figures.

Figure 1 is a front View of my machine. Fig. 2 is a side View thereof. Fig. 3 is a detail View of the cutters, punch device, and stripper. Fig. 4 is a detail of bolster and shifting device. Fig. 5 is a detail of guide device for supporting end of wire. Fig. 6 is a detail of wire out 01f and flattened. Fig. 7 is a detail View of the wire with the hole punched in the head thereof and the head rounded and smoothed off; and Fig. 8 is a detail view of shifting device, showing wires in position to be cut off, flattened, and punched.

As is seen by reference to Fig. 1, the feed mechanism is secured to and at the side of the body of the press A. The frame A holds the rollers 1 and 2 of the feed mechanism, 1 being theguide-wheel for top of wire, and 2 being the guide-wheel for the bottom of the wire. The connecting gear-wheels 3 and 41ntermesh, and, together with the ratchet-wheel 6, which hasaratchet-plate 5, are driven from the crank-arm a of the press by means of the connecting-rod 8.

On the shaft of the gear-wheel 3 is a fixed bevel-gear 13, which meshes with a similar bevel-gear 12 on the shaft of the ratchet-wheel 6, as is shown by dotted lines in Figs. 1 and 2.

A driving-plate lO-is secured on shaft a, and 11 is a screw for adjusting the stroke of the rod 8, by which the length of the lingo is regulated. The contact of the wheels 1 and 2 is adjusted or regulated by means of the pressure-screw 14.

The ram A, the bolster bloek B, and the bolster B are the same as in the ordinary press. c

B represents the raised surface of the bolster.

I provide the press with a straight cuttingknife 0 anda rounded cutting-knife c. The bolster has a straight edge e and a round edge e to correspond with the cutters'c and c. The press is also provided with the punch 11. I attach to the press a device for shifting the wire and also a stripping device. The shifting mechanism is operated by the lever 19, the central portion of which is pivotally secured to the framework of the press. The lever 11 is operated by the cam 61 on the shaft a, the cam 01 coming in contact with the roller d on said lever b. A spring S, secured to the stand of the press and the lower end of the lever 19, keeps the roller d in constant contact with the cam cl. To the bottom of the lever 19 is pivotally secured a shifting hook f, as indicated at f, and said shifting hook f is pressed down in place by means of a spring f which is attached to the lower portion of the lever b. The hook fis provided on its under side with an extended portion f, as shown in Fig. 8. A vertical stripping-rod n slides in clips 02 and is provided at the bottom with a horizontal portion at right angles to the vertical rod, the end of which, n, encircles the punch a. The stripper-rod n is operated by the strap a of the connecting-rod a as is shown in Figs. 1 and 3.

Secured to the bed-plate of the machine is the standard g A movable arm 1) is pivoted thereto, said arm having the hole 00 through which the wire is conducted to the cutters and punch. A spring 19 surrounds the rod 13' and gives a tension to the arm at its outer end, allowing the same to move in unison with the action of the cutters. The wire being fed is represented by the reference-letter 0c, and a," is the wire cut off, forming a lingo. The wire after being cut off is fed laterally over the surface of the bolster by means of the hook portion fof the shifting device.

Power being applied to the press in the ordinary manner, the operation of my machine is as follows: The wire is intermittently fed by the wheels 1 and 2 of a sufficicnt length to form a lingo, passing through the guide-hole (.62 in the guide 19 and onto the bolster B and the supporting-block 7t and under the angle part of the shifting hookfof the shifting device. The ram A, carrying the cutters and punch, descends. The cutter c severs the wire and at the same time flattens the end on the bolster B The rotation of the crank-shaft 0 brings the ram A upward, and at the same time the cam d by contact with the pivoted lever b forces the shifting device f, which carries the wire at, over the bolster to the stop is and in line with the rounded part 0 of the bolster. The punch n and the cutter c then descend, and the wire is simultaneously punched through the flattened portion and has its end cut 0% round and smooth. During the cutting and punching the shifting device recedes to its original position, the projecting part f is forced over the finished lingo, which is still held by the punch, and the intermittent-feed mechanism again feeds sufficient Wire to form another lingo, the above-described operation being repeated. As the lingo is apt to cling to the punch 11., it is removed as follows: The stripper-rod n is pressed downwardly by the motion of the strap a, and the end it of the stripping device which encircles the punch 01, forces the completed or finished lingo therefrom; It is obvious that the lingo and the stripper-rod rise with the punch until the strap a in its descent forces the stripper-rod downwardly, releasing the lingo from the point of the punch. These operations are continued until the supply of wire is exhausted. The completed lingo maybe removed from the bolster by hand.

Vith this description of my invention, what I claim is- 1.
